| Whether a bright state or a dark state is established is determined each time a motor is driven one step, based on a presence or absence of a passing of light through a detection hole disposed in a detection wheel that rotates associated with rotations of a hand wheel coupled with the motor. A switching position X is identified at which the dark state is switched to the bright state when the dark state is determined and thereafter the bright state is determined. A position one step after the identified switching position X is set to be a reference position X+1 of the hand wheel. The reference positions X+1 and X−1 can thereby be set after a driving mechanism is assembled. | ||||||

| To make a time instant correction possible while suppressing an electric power consumption due to a reception of radio wave containing a time instant information. When a reception means has been made into its operation state in order to receive the radio wave containing plural markers disposed in predetermined positions and the time instant information, in a case where.the marker initially received has been a reference marker M corresponding to an exact minute position, the time instant information is obtained by continuing the reception intact, and a time instant of a clock means is corrected and displayed to a display means. When the marker initially detected has been a position marker P, the reception means is made into its non-operation state. After 9 seconds from this point in time, the reception means is made again into the operation state in order to receive the reference marker M appearing after a constant time. This operation is repeated till the reference marker M can be detected, thereby performing the time instant correction. | ||||||

| To improve the accuracy of a clock signal. The phase of a clock signal output from an SAW oscillator 3 is corrected by a phase control section 8 so that a signal synchronizing with the carrier wave of a standard time and frequency signal, that is, a carrier wave signal phase-synchronizes with a clock signal. Therefore, when a standard time and frequency signal can be received, it is possible to correct a clock signal in accordance with a carrier wave signal which can be generated from the standard time and frequency signal anytime. Therefore, even if operational environments (for example, temperatures) of the SAW oscillator 3 are changed and the phase of a clock signal output from the SAW oscillator 3 is fluctuated due to the change, it is possible to synchronize the fluctuated clock signal with a standard time and frequency signal, that is, the carrier wave of a radio wave for providing a very accurate frequency standard and time service signal and as a result, it is possible to improve the accuracy of the clock signal in accordance with the correction. | ||||||
| 75 | Method for operation of a radio-controlled clock and radio-controlled clock for use in an environment subject to interference fields | US102244 | 1993-08-05 | US5349570A | 1994-09-20 | Reinhold Kaiser |
| A method for operation of a radio-controlled clock comprising a quartz-controlled clock synchronized by a time signal receiver with a time signal via a signal processor. In a common array with an additional device, such as a computer or television set, reception of the time signal is generally largely prevented by the interference effect of the additional device. In the method in accordance with the invention, the quartz-controlled clock is therefore synchronized with the time signal solely when the additional device is no longer generating an interference field. For this purpose, a detector is provided that recognizes the operating state of the additional device and permits synchronization of the quartz-controlled clock with the time signal only when the additional device is not generating an interference field, or if so only a reduced one. Furthermore, a radio-controlled clock is described that is suitable for operation by the method in accordance with the invention. | ||||||
